RELATED APPLICATION

This application claims the benefit of priority under 35 USC 119(e) of U.S. Provisional Patent Application No. 61/656,548 filed Jun. 7, 2012, the contents of which are incorporated herein by reference in their entirety.

BACKGROUND

The present invention, in some embodiments thereof, relates to user modeling, and, more specifically, but not exclusively, to user modeling employing component based approach.

As systems' complexity increases the need for modeling tools, services and/or frameworks becomes more evident. Current systems, tools and/or tools for creating user models (representing one or more users) usually are based on proprietary concepts, allowing a developer of the user model to develop user models (UM) in an ad-hoc manner for the following main reasons:

-   (i) System developers focus on specific characteristics of their     users in order to deliver a specific service. -   (ii) The user modeling community does not have commonly accepted     standards and/or frameworks for user model development and/or user     model structure. -   (iii) User model components, i.e. user model building blocks are not     publicly shared for reuse. -   (iv) Developing a standard user model that holds a comprehensive set     of attributes requires a major effort to be carried out in by a     single organization, facility and/or vendor.

As the user modeling research advanced it suggested moving away from complete monolithic solutions and/or user modeling ontological representations towards partial and/or dynamic solutions providing modular architectures supported by mediation techniques to support some level of interoperability.

One modular approach is component based development which supports development of complex user models by dividing them into independent components. Component-based development approach focuses on sharing and reusing components which potentially improve efficiency of system design and development. A component may be represented as an abstract box that encapsulates its properties and/or processing. The component may hold information, be sensitive to events and context, and supply services, which are constrained by conditions.

DETAILED DESCRIPTION

The present invention, in some embodiments thereof, relates to user modeling, and, more specifically, but not exclusively, to user modeling employing component based approach.

According to some embodiments of the present invention there are provided systems and methods for developing a user model employing component based approach by dividing the user model into small, standard and reusable multipurpose building block software components having a common structure that may be integrated to create an abstract user model. The component based approach is an incremental approach for user modeling which is based on defining the building block software components as reusable units for deployment and composition of the user model.

A user model includes a plurality of concepts in which the concepts are composed of one or more of the plurality of software components. The user model is developed by selecting the software components that implement the characteristics and/or features required by the user model. The software components may be retrieved from one or more component collections.

Optionally, group models are modeled using the component based approach to support modeling of a group comprising of two or more user models. The group model may include and/or present characteristics and/or attributes induced from the relationships and/or impacts between two or more of the user model the group model includes.

According to some embodiments of the present invention there are provided systems and methods for creating a plurality of software components to be used for constructing the user model. The software components are created using a common structure so as to maintain a standard representation of the software components. Each of the software components is associated with a single attribute. The component is a small bounded unit which is capable of receiving data through one or more input ports, processing the data to generate an attribute data, storing the attribute data after time tagging it and allowing access to the attribute data from other software components through a single output port. The component may include metadata which holds additional information that relates to the component, for example, software component type, user model or group model identification data, model instance identifier, definition of the attribute and/or software component behavior explanations.

Optionally, the component is capable of generating default attribute data without receiving data from the input port(s).

Optionally, the component may store a plurality of specific attribute values each paired with a time tag to provide multiple values of the attribute over time.

The plurality of software components constituting the user model is connected among themselves with data links according to the concept, capability and/or feature they are required to present. The data link represents a communication and/or interface channel among the software components and/or between the software components and service applications that need the software component information content. The data link defines the flow of data through the user model and delivers attribute data from the software component to a consumer (e.g., another software component and/or another application) as a tuple. The tuple may include a plurality of additional data items, for example, the origin component identification, the sending time and/or a collection of time tagged values of the software components' attributes.

Optionally, the user model and/or the group model hold design information relating to the software components and/or the data links implementing and/or organizing the user model and/or group model respectively.

Dividing the user models into simple and/or small software components may enable the recruiting the effort of a plurality of vendors, organizations and/or sites to map and generate these software components. The software components may be aggregated into a publicly available collection(s). The software components, their dynamically expanding collection and relevant methodologies could become a user-modeling standard supporting component suppliers, user model developers to develop user models and service applications designers using the developed user models for creating their service applications.

Reference is now made to FIG. 1 which is a flowchart of an exemplary process of creating a user model using component based approach, according to some embodiments of the present invention.

As shown at 101, an exemplary process 100 of creating a user model using component based approach employs creation of a plurality of software components. All software components of the plurality maintain a common structure and are each associated with a single attribute of the user model. The plurality of software components may be stored in a shared collection which may be available to a plurality of developers each constructing their own user model.

As shown at 102, a user model is constructed using the plurality of software components to represent one or more concepts of the user model according to the required capabilities, features and/or characteristics of the user model.

As shown at 103, once the user model is created it may be outputted in one or more of a plurality of presentations. Presentations may include, for example, visual presentations to be presented to the developer, for example, through a display, screen, hard copy and/or printout. Presentations may also include digital format in the form, for example of a binary file for the purpose of, for example, storage of the user model in a storage medium and/or for making the user model available to other systems and/or software tools and/or applications which desire to make use of the user model.

The created user model may include an execution mechanism which may be used to instantiate the user model with specific information of one or more users. Instantiation of the user model may be performed at any stage after the user model is created and outputted. The created group model may also include an execution mechanism which is used to instantiate the user model with group member user model that are instantiated for specific users.

Optionally, as shown at 104, a group model is created which includes two or more user models where each of the user models is created using the process 100.

Optionally, as shown at 105, instantiation of the user model may be performed in which values related to one or more specific users are assigned to the various attributes of the software components of the user model to perform, for example, system exploration, information utilization, evaluation, optimization, adaptation and/or improvement.

Optionally, as shown at 106, instantiation of the group model may be performed in which values related to a group and its members are assigned to the various attributes of the software components of the group model to perform, for example, system exploration, information utilization, evaluation, optimization, adaptation and/or improvement.

Reference is now made to FIG. 2 which is a schematic illustration of an exemplary design space for constructing user models by employing component based approach, according to some embodiments of the present invention. An exemplary design space 200 may be used for constructing a plurality of user models 220, 221 and 222 each serving one of a plurality of applications 230, 231 and 232 respectively. Each of the user models 220, 221 and 222 may be constructed using a subset of the software components available in a component collection 201. The user model 220, for example, is constructed of software components 202, 203, 204, 205 and 206 where each software component provides a single attribute. The software components, 202, 203, 204, 205 and 206 are connected among themselves with data links. The data links define the flow of information through the user models 220, 221 and 222. Each of the software components may receive input attribute data from one or more other software components, as shown for example for the software component 206 which receives attribute data input from four software component, 202, 203, 204 and 205. However, a software component may generate a default attribute data, for example when data input is not available, as is shown for example, for the software component 205 which has no input data link. Each of the user models 220, 221 and/or 222 may be constructed using a different subset of the software components available in the components collection 201. The user models 220, 221 and/or 222 may use the same software components in different contexts to represent different capabilities, features and/or characteristics as required by the developer.

Some embodiments of the present invention, are presented herein by means of an example, however the use of this example does not limit the scope of the present invention in any way.

Reference is now made to FIG. 3 which is a schematic illustration of an exemplary design space for constructing user models employing vital signs sensors, according to some embodiments of the present invention. An exemplary design space 300 may be used for constructing three user models 320, 321 and 322 each serving one of a plurality of applications, for example, a medical service application 330, an experience enhancement service application 331 and a sportswear sales service application 332 respectively. The three user models 320, 321 and 322 share software components, for example, pulse sensor 301, heartbeat sensor 302, average pulse 303 and/or average heartbeat 304 which are available from a component collection such as the component collection 201. The user models 320, 321 and 322 also use additional software components, for example, health 305, excitement 306 and/or fitness 307 which are employed to support the context and/or concept of the user model.

As can be seen in the exemplary design space 300, the context of the medical service application 330 requires the user model 320 to provide health indication. Therefore the user model 320 implements software component composition to support that context and provide current vital signs readings as well as average readings. The software component health 305 receives attribute data from all the other software components in the user model 320, i.e., the pulse sensor 301, the heartbeat sensor 302, the average pulse 303 and the average heartbeat 304 to process attribute data of the software component health 305 and make attribute data available to the medical service application 330.

The context of experience enhancement service application 331 requires the user model 321 to provide only current vital signs readings. Therefore the user model 321 implements software component composition to support that context and provide current health readings as well as average readings. The software component excitement 306 receives attribute data from the pulse sensor 301 and the heartbeat sensor 302 to process attribute data of the software component excitement 306 and make the attribute data available to the experience enhancement service application 331.

The context of the sportswear sales service application 332 requires the user model 322 to provide averaged pulse and heartbeat indications. Therefore the user model 322 implements software component composition to support that context and provide average vital signs readings. The average pulse 303 and the average heartbeat 304 software components receive attribute data from the pulse sensor 301 and the heartbeat sensor 302 respectively and process it to create their own attribute data. The attribute data of the software components average pulse 303 and the average heartbeat 304 then make their attribute data available to the software component fitness 307 which manipulates it to create its own attribute data which may be used by the sportswear sales service application 332.

According to some embodiments of the present invention there are provided systems and methods for creating the plurality of software components to be used for constructing the user model. Each software component is s a small bounded unit and is associated with a single attribute. The software components employ a common structure.

Reference is now made to FIG. 4 which is a schematic illustration of an exemplary software component, according to some embodiments of the present invention. An exemplary software component 400 includes the following objects, input ports 401, attribute generation engine 402, attribute repository 403, attribute access 404, output port 405 and metadata & tools 406. Each of the objects, the input ports 401, the attribute generation engine 402, the attribute repository 403 and the attribute access 404 is optional and may not be present in the software component 400. Presence of the objects may depend on, for example, the functionality of the software component 400, the purpose the software component 400 serves and/or the interaction it may require with one or more other software components. The software component 400 may receive, through the input ports 401, input attribute data from one or more other software components, sensors or human-machine interfaces which precede the software component 400 in the user model composition. The attribute generation engine 402 may contain executable software program instructions, firmware or hardware configured to manipulate the received input attribute data to generate attribute data of the software component 400. Manipulation of the received input attribute data may include, for example, processing the received input attribute data, inferring attribute data from the input attribute data and/or leaving the input attribute data as is. The attribute repository 403 is used to store the attribute data of the software component 400. Other software components which succeed the software component 400 in the user model composition may access the attribute data of the software component 400 through the output port 405. The attribute access 404 controls the access to the attribute data so as to verify whether the accessing service and/or software component is authorized to access the attribute data, based on a plurality of considerations, for example, privacy and/or hierarchy. The metadata & tools 406 holds a component identifier used to identify the software component. The metadata & tools 406 may hold additional information that relates to the software component 400, for example, definition of the attribute (such as help functionality) and/or component behavior explanations, interfaces allowing other software components and/or services to use the software component, tools to control the data (e.g. update and/or delete), interfaces for tools that use software components in models' design. The software component's metadata enables a user model developer to search and select the software component 400 that is required for his user model through the metadata description of the software component 400 and to understand the behavior of the software component 400.

Optionally, the attribute generation engine 402 is capable of generating default attribute data without receiving data from the input ports 401, for example in the event no software component is connected to the input ports 401.

Optionally, the software component 400 may hold, through the attribute repository 403, a plurality of attribute data values. Each of the plurality of attribute data values is associated with a time tag to provide multiple values of the attribute over time.

Optionally, the software components 400 are selected from a component collection such as the component collection 201. The component collection may be utilized through, for example, local storage medium, remote storage and/or online database.

The plurality of software components 400 composing the user model are connected among themselves by the data links which define the information flow within the user model. The composition of the software components and their connections serve the concepts, capabilities and/or features that are required by the user model. The data link between the software components 400 may hold composition information relating to the software components' implementation and/or organization within the user model composition. The composition information is delivered from one software component to the next as a tuple. The tuple may include a plurality of data items, for example, the origin component identification, the sending time and/or a collection of time tagged values of the software components' attributes.

Reference is now made to FIG. 5 which is a schematic illustration of an exemplary design environment for developing and instantiating user models using component based approach, according to some embodiments of the present invention. An exemplary design environment 500 presents the sharing and reusability provided thought the component based approach. A plurality of software components 520 may be available in one or more component collections such as the component collection 201. The plurality of software components 520 may include software components 400 and/or software component compositions containing two or more components 400. The component collections 201 may be stored in a shared location, for example, computer, workstation, server, cluster of processing nodes and/or storage cloud such that the component collection(s) 201 are available to a plurality of user model developers. The plurality of users and/or user model developers may create a plurality of user models 501, 502 and/or 503 using the software components 520 as required to meet the requirements of the user models 501, 502, 503 and/or the applications the user models 501, 502 and 503 serve. Once the user models 501, 502 and 503 are created they may be executed and be instantiated to be used for information utilization, evaluation, explorations, optimization, analysis, adaptation and/or any other improvement for specific cases for one or more specific users. The instantiations 510, 511 and 512 are example instantiations of the user model 501 in which specific attribute data values are assigned to each of the instantiations 510, 511 and 512.

According to some embodiments of the present invention there are provided systems and methods for creating a group model using the component based approach. The group model includes one or more user models which are combined into a single model so as to model the characteristics, behavior and/or features of each of the user models within the group model. In addition it may optionally implement software components for group attribute (a group attribute is an attribute that is not relevant for a single user, such as being part of the same family).

Reference is now made to FIG. 6 which is a schematic illustration of an exemplary group model using component based approach, according to some embodiments of the present invention. An exemplary group model 600 is a combination of group member user models, 610, 611 and 612 and a model of the entire group 600. Each of the user models, 610, 611 and 612 is constructed using the software components 400 and contains group attributes 620 relating to the concept expressed in each of them. Instantiation of the user models 610, 611 and/or 612 for a specific case and/or user as stand alone may be different compared to instantiation of the same case and/or user in the company of other users and/or a higher level implementation. In the context of groups, the same user model may have different instantiation in different group models, for example, person may behave differently in the presence of his family compared to his behavior in the company of work colleagues. Attributes of the group members, for example, age, desires and/or personality may affect the behavior of the group members. In addition user models 610, 611 and/or 612 may behave differently when combined together in subgroups 601, 602 and/or 603 within the group model 600.

The attributes of the group model 600 may be represented through the following:

-   -   (1) The attributes 620 of the entire group model, for example,         group types (family, friends and/or work), group interest (task         and/or leisure activity) and/or group state (conflict, same         location, separate locations and/or interaction).     -   (2) Description of the changes in a group member when the group         member joins the group.     -   (3) Description of the group member user model 610, 611 and/or         612 in the company of only a members' subgroup models 601, 602         and/or 603 of that group model. An example may be two couples         walking together as a group in a mall, and then separate into         two subgroups; such as the first subgroup includes the two         females and the second subgroup includes the two males.

The component based approach supports group modeling as it allows, for example, representation of the three aspects of the group model 600:

-   -   (1) Utilization of the attributes of each of the user models         610, 611 and 612 as standalone.     -   (2) Utilization of the group attributes 620 and the user models         610, 611 and 612 when joining the group model 600.     -   (3) Utilization of the group attributes 620 and the user models         610, 611 and 612 when participating in each of the subgroup         models 601, 602 and/or 603. Each of the subgroup models 601, 602         and/or 603 may have additional software components 400 that hold         attributes of the respective subgroup.     -   (4) Utilization of the attributes 620 of the entire group model         600. The group model may include only a subset of the software         components 400 included in the group members user models 610,         611 and/or 612 and therefore the attributes 620 may relate to         only the included subset of software components 400.

Using the component based approach for developing group models allows using software component 400 to represent group traits, subgroup models traits and individual user models traits.

Reference is now made to FIG. 7, which is a schematic illustration of an exemplary system for creating a user model employing component based approach, according to some embodiment of the present invention. A system 700 is a processing unit that includes a processor 710 capable of executing program instructions, for example, computer, server, workstation, cluster of processing nodes and/or cloud processing. The processor 710 executes several software modules, each responsible for a performing part of the overall modeling process such as the process 100. A user interface module 701 interacts with the user model developer for creating the user model using the software components 400 and/or software component compositions and linking. A software component creation module 702 is used to create the software components 400 according to the software component structure described hereinabove. The software component creation module 702 may interact with the user model developer through the user interface module 701. Interaction with the user model developer may be utilized through a plurality of human-machine interfaces, for example, keyboard, pointing device, touch screen and/or audio commands. The software component 400 that are created may be stored in a component collection such as the component collection 201. The component collection 201 may be implemented in a plurality of architectures, for example, local storage, remote storage, centralized storage, distributed storage, server and/or cloud storage. A modeling module 703 is performing as the engine for modeling the user model and/or the group model interactively with the user model developer using the user interface module 701. An output module 704 outputs the user model. The user model may be output to be presented to the user model developer and/or to be used in additional modeling, analysis, optimization, evaluation exploration, adaptation, improvement, and/or instantiation for information utilization.

The user model may be output in a plurality of representations, for example, visual representation and/or digital representation. Visual representation may be utilized through the user interface module 701 and may include, for example, display and/or printout. Digital representation may include, for example, binary file and/or data structure. The user model further includes an execution mechanism which may be used to instantiate the user model with the specific information of one or more users. Instantiation of the user model may be performed at any stage after the user model is created and outputted.

Optionally, the system 700 includes an execution module 705 which may instantiate the user model for specific one or more users. The execution module may also instantiate group models for a plurality of group member user models instantiated with a plurality of specific users.

According to some embodiments of the present invention, there is provided a computer program product for creating the software components 400, software component compositions and/or for creating a user model and/or group model using the software components 400 and/or the software component compositions. The computer program follows the process 100 and may be executed over the system 700.

Reference is now made to FIG. 8A which is a screen capture of an exemplary software component selection screen of an exemplary user model editing tool, according to some embodiment of the present invention. As seen in the screen capture 801, once the software components are available in one or more component collections such as the component collection 201, located in a local storage medium and/or at remote storage, the user model developer may drag and drop the software components into the working area. As In the example presented in the screen capture 801, the user model developer may drag and drop a plurality of software components, blood pressure, pulse, current pulse, average pulse, current blood Pressure, average blood pressure and excitement to the working area. Each software component behaves differently when activated. The pulse software component provides an API (Application Programming Interface) to read a pulse sensor data of a user and it sends the pulse sensor data as reported by the sensor, for example, pulse readings, erroneous reports, measurement noise, missing data and/or outliers. The current pulse software component smoothes and validates the pulse sensor data and reports only valid data. The average pulse component uses the current pulse reported data as input, and calculates, for example, an annual average pulse. The software components related to blood pressure repeat the same process for blood pressure. The excitement component analyzes the user's level of excitement by comparing, for example, the current pulse to the average pulse, the current blood pressure with the average blood pressure and/or combining comparisons of the two. The user model editing tool automatically generates allowable dataflow links between the selected software components, represented by directed dashed arrows.

Reference is now made to FIG. 8B which is a screen capture of an exemplary data links editing screen of an exemplary user model editing tool, according to some embodiment of the present invention. As seen in the screen capture 802, once software components are selected, the user model automatically presents all valid links, and the user model developer approves the required data links. Upon instantiation of the user model to one or more specific users, data would flow only through the approved data links. Approved data links are shown as solid arrows. In the example presented in the screen capture 802, the developer of the user model uses only pulse data for analysis by the excitement software component. The data related to blood pressure is available by the blood pressure, current blood pressure and average blood pressure software components within the user model, however this data does not flow to the excitement software component as the appropriate data links are not approved (shown as dashed arrows). The user model developer may save the model through the user model editing tool menu. The saved user model may be instantiated for one or more specific users. The instantiated user model is a copy of the generic user model and may be stored in a storage medium, locally and/or remotely. The instantiated user model is capable of reporting pulse raw data, pulse smoothed data, blood pressure raw data, blood pressure smoothed data, average pulse, average blood pressure and/or excitement level.
